ChainSafe Systems is a blockchain R&D firm on a mission to realize the potential of Web3 infrastructure through sustainable, open-source development. Our vision is to create a world with organizations that empower people to build and innovate through blockchain agnostic tools and other distributed technologies.
We are global leaders in the industry, unique in our work across multiple blockchain ecosystems, and currently are pioneering Ethereum, Ethereum Classic, Cosmos, Polkadot and Filecoin technology. We are actively pursuing the development of our own product suite, having recently released Files, which allows users to upload and store files on IPFS and Filecoin with the goal of furthering development to provide a decentralized alternative to cloud storage.
ChainSafe is a unique company in a unique space, growing quickly and building a global reputation in this nascent space. Beyond offering experience across every major blockchain space to our team, we provide an open, inclusive, and supportive environment where we help folks reach their full potential as a human and as a professional.
Here’s what you might want to know before reading on:
- Our stack is progressive and open-source and includes Go, Rust, and TypeScript.
- We spearhead ecosystem projects like Lodestar, Web3.js, Forest, Gossamer and Ethermint.
- We are global, remote-friendly, and open to contractors (who can commit to a minimum of 35 hours a week). For those local to Toronto, our casual, open-concept office in Chinatown has meeting rooms, lounge areas, and space to pull up a chair.
Culture fit and alignment to our core values are extremely important to us. We are fueled by an immense intellectual curiosity of what technology can do and the impact it can have. You will thrive here if you are intensely driven by tackling technical challenges that no one else has solved yet and are inspired by the possibility of building the next generation of web infrastructure and decentralized systems.
